Answer 1

a) 14 hours

b) 10.5 hours

Explanation:

42 hours = 1 week

a) 1/3 hours a week dealing with complaints

`(1)/(3) *(42)/(1) = (42)/(3) = 14`

He spends 14 hours a week dealing with complaints.

b) 1/4 hours a week on the phone

`(1)/(4) * (42)/(1) = (42)/(4) = (21)/(2) = 10.5`

He spends 10.5 hours a week on the phone.

Answer 2

a). 14 hours a week

b). 10.5 hours a week

Explanation:

His time = 42 hours a week

Quarter of his time = one fourth of his time.

Third of his time = one third of his time

So, for dealing with complaints:

42h * 1/3 = 42h / 3 = 14h

On the phone:

42h * 1/4 = 42h / 4 = 10.5h
